HITOP 500W Aquarium Heater with Temperature Display, Submersible Fish Tank Heater with Adjustable Button for 100-200…

[Top grade Material for Heating Elements]: 500W, 10.6*2.8*1.2 inches, Ni-cr Alloy heating element, eliminated the disadvantages of easy-broken of quartz glass, characterized by high resistivity, thermal fatigue resistant, corrosion resistance and high temperature shape stability, top grade heating element for heaters.
[Real-time Water Temperature Monitor]: Dynamically display real-time temperature, convenient to monitor the water temperature. Adopting an 100K 10% internal high-efficiency temperature sensor, more accurate and rapid to detect temperature fluctuations. More reliable and longer service life.
[External Temperature Adjuster]: External circulating temperature control device, 60℉~93 / 16℃~34℃, more convenient and safer.
[Automatically Cut-off when Leave out of Water]: Equipped with Auto-off device,the heater will power off automatically when leaving water,it’s much safer to protect people and fish.
[More Accurate Temperature Control]: Heating part is separated from electric parts, this can protect and lengthen the life of the electric elements, also can make the temperature controlling more accurate, error ±1℉/0.5℃.
